Communications InfrastructureInternetInternet of ThingsMobileTelecommunications
Responsibilities
Detection Engineering: Design, build, and optimize advanced security detections within the Splunk platform. You will move beyond basic alerts to create high-fidelity, risk-based alerting (RBA) models that identify complex attack patterns
EDR Strategy & Management: Serve as the global SME for our CrowdStrike environment. This includes managing large-scale deployments, tuning prevention policies, and performing deep-dive forensic analysis on endpoint telemetry
Linux Security Mastery: You will work primarily on linux-based systems developing detections and investigating EDR-based alerts and detections
Data Engineering: Analyze, normalize and utilize data to identify certain security patterns and properties
Scripting and Coding: Build small programs and scripts to solve problems and automate tasks to allow the team to move faster and be more efficient
Qualification
Required
Bachelor's degree in Computer Science, Cybersecurity, or a related field or four or more years of work experience
Six or more years of relevant experience required, demonstrated through one or a combination of work and/or military experience, or specialized training
Principal-Level Cybersecurity Foundations: A 'first-principles' understanding of cybersecurity, from memory corruption and buffer overflows to global identity-based attacks
Endpoint Expertise: Deep experience managing EDR/XDR detections at scale. You should be comfortable pivoting from a high-level alert to raw process trees and memory strings to validate a threat
The Linux Specialist: You are intimately familiar with the Linux boot process, system, PAM, and how attackers leverage them for persistence. You can process audited logs and quickly find the anomaly
Network Intelligence: Advanced knowledge of networking protocols (BGP, TLS/SSL, DNS)
Programming/Scripting: Expert knowledge in developing scripts and writing programs (e.g. Python) to automate tasks and solve problems
Data Engineering: Advanced knowledge of database systems, the relational database model and hands-on expertise working with data
Extensive experience in a dedicated security engineering or incident response role, with a track record of defending enterprise-scale environments
Strong analytical skills and attention to detail with a proven track record of managing and delivering results
Leadership experience as a subject matter expert with effective written, interpersonal, and verbal communication skills
Preferred
Splunk Proficiency: Expert-level knowledge of Splunk SPL. You should be capable of building custom macros, data models, and automated lookups to streamline investigations
Attack & Mitigation Knowledge: You don't just know what a 'Golden Ticket' or 'Living off the Land' attack is; you know exactly what telemetry is required to block or detect it
Preferred Tools: Hands-on experience with CrowdStrike Falcon (including RTR and Fusion) and Splunk ES is highly preferred
